Here's what i predict.
Nintendo
Good - The Wii U might catch up in sales because of the Christmas line up of games this year and 2014's fantastic quality games, Ubisoft still might be with them, hopefully get 2 or 3 major 3rd party games, and the 3DS becomes the dominate handheld system ever.
Bad - I predict is that they might go full on digital, cause if you look at sales numbers, the digital sales sell more and physical copies can barely catch up. So kiss those game cases, disks or cartridges cause they might be gone on Nintendo systems.
Sony
Good - Finally stop releasing new IPs involving zombies and shooters and get the most popular games made for PS4 like Uncharted 4 and REAL God of War 4 this time.
Bad - Still calling the Vita the 'Ultimate handheld experience' while still having no major exclusive 'I NEED A VITA!' game for the thing, and they might change their mind about Indie developers.
Microsoft
Good - hopefully repair all the damage they've done having new and trustworthy faces and having a really good online and paying big money for exclusivity.
Bad - Not doing anything what i said about my good statement.
